ruby-on-rails-3 - Ubuntu 64 位 11.04 上的 Heroku 和 RoR 服务器

Question

所以我想将我的应用程序部署到 Heroku，注册帐户并做其他必要的事情。但是我在运行命令 heroku keys:add 时遇到了问题。这是我得到的错误:

ruby@Rubuntu:~/rails_projects/first_app$ heroku keys:add
/home/ruby/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': no such file to load -- readline (LoadError)

请帮帮我!

附言!我正在使用这本书学习 RoR: http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec:install_rubygems
